The things I've done with this is amazing and I can't imagine running without out. Their answer was just mail it back to us and we'll replace the battery. Yea cause that would be so easy. The entire system including my ATO runs off of it. Let me just shut everything down for 2 weeks while you replaced a $2 battery. For $500+ I guess I would expect better from them. I'm rewritting some code to compensate for this issue. If I can work out a few bugs it will be business as usual and I leave it as is for now.
